And the Rebirth Brass Band, which won a Grammy this year, closes out the festival at 6:30 p.m. Sunday. But these three acts barely scratch the surface of all the music at this year's festival.

Art Cars Show & Parade You think polishing your car every week shows how much you love it? Here are some people who love their cars so much, they turn them into traveling works of art.

It's scheduled to hit the intersection of North and Mount Royal avenues at 11 a.m. Many of the cars will be on display throughout Artscape, which doubles as the site of the 19th annual Art Car and Other Wheeled Vehicle Show.

Performances are set for noon, 2 p.m., 4 p.m. and 6 p.m. daily at Charles and Preston streets, with each show preceded by a parade.
